Acousto-Optic Filter Soliton Control

In analogy with the sliding filter method that was invented by L F Mollenauer et al, the soliton stability in a periodically amplified transmission system may be controlled by inserting before each amplifier a properly designed acousto-optic wavelength shifter and a filter. We also propose and experimentally demonstrate the application of this principle for the generation of picosecond pulses in a fibre loop laser
